About the Airtac SAI40 Standard Air Cylinder SAI40X475S
The AirTAC SAI40X475-S is a double-acting ISO 15552 profile cylinder engineered for precise linear motion. Delivering 628N of push force at 0.5 MPa, this unit is built around an extruded aluminum barrel that eliminates tie-rods for a cleaner profile. The 475mm stroke provides the extended travel needed for material handling and automated assembly tasks.
This specific configuration includes a magnetic piston for position sensing, seamlessly integrating with CMSE or DMSE reed switches along the integrated sensor grooves on both sides of the barrel. The standard carbon steel piston rod offers robust durability for industrial environments, while the adjustable air cushions at both ends absorb impact energy at stroke endpoints.

Where the Airtac SAI40 Standard Air Cylinder SAI40X475S Is Used
Material Transfer
Drives extended pushers on packaging lines where the 475mm stroke moves cartons between conveyor belts efficiently.
Assembly Automation
Actuates multi-stage indexing stations, utilizing the 628N force to seat components over long travel distances.
Warehouse Sorting
Powers diverter arms on logistics sortation systems, relying on CMSE sensors to confirm full extension and retraction.
Is the Airtac SAI40 Standard Air Cylinder SAI40X475S the Right Cylinder?
When sizing this model, stepping down to a 32mm bore reduces the 0.5 MPa push force to 402N, whereas moving up to a 50mm bore increases it to 982N. The 475mm stroke requires careful attention to structural support; long unsupported rods are susceptible to bending under side loads. Implementing an external guide rail or selecting a guided cylinder module is strongly recommended to prevent premature rod-bearing wear.
As a true ISO 15552 profile cylinder, this model serves as a drop-in replacement for any standard cylinder sharing the 40mm bore, 475mm stroke, PT G1/4 port, and FA/FB flange or LB foot mounting dimensions. Note that standard SAI cylinders do not hold position upon air loss; for suspended loads requiring safety locking, consider the SAIL or BSAI variant instead.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI40 Standard Air Cylinder SAI40X475S FAQ
At 0.5 MPa operating pressure, the SAI40X475-S generates 628N of push force and 528N of pull force. At 0.7 MPa, the push force increases to 879N.
Yes, the SAI40X475-S is manufactured to the ISO 15552 standard, making it dimensionally interchangeable with other ISO 15552 profile cylinders of the same 40mm bore and 475mm stroke specifications.
